Nice, thanks for sharing it. I tried it and it works fine, the response feels fast there's possibly a little bit of lag if you very quickly give pot0 a full turn but nothing to worry about.

Once you have made pot1 select the intervals it will be a very nice effect.

Just for a laugh I thought I'd try and do something similar to Jonny Greenwood's Max MSP random delay effect. In case you've never heard of it here's a youtube clip of it in action http://www.youtube.com/watch?v=xyKCwDJ7ZUc It's based on Franks record/play example here http://www.spinsemi.com/forum/...

Using LDAX just means you don't need to worry about what was in the accumulator from the previous instruction. I use it as a fail safe, in the event that I've not cleared the accumulator with the previous instruction. Or like the example on the website, there might be times when it saves you a line ...

I haven't gone through the whole thing but I think the reason you're getting no output is here wrax phaout, 0.0 ;write result to phaout and clear acc ; sof 1.999, 0 ;scale gain back up wrax dacr, 1.0 ;write to right output, save accumulator wrax dacl, 1.0 ;write to left output, clear acc You're taki...

Thought I'd share this flanger I've been working on. Still needs some work, I'm not happy with the speed range of the LFO and the code needs tidying up a bit. Hopefully the comments explain what's going on. Big thanks to Frank and everyone else who worked on the knowledge base and anyone who's contr...

I think this is what Frank meant. It gives you 8 bit "white noise", you can change the AND mask to give more or less bits ie: and %000000000000000000001111 would be 4 bit. I haven't experimented to see what the maximum number of bits you can use is before it stops being noise. rdax adcl,1 ...

Here's a simple sawtooth generator, there's probably much better ways to do it, but it works Ok. If you wanted you can use the saw to generate other waveforms, rectify it to get a triangle, clip this to get a sine, compare it to something to get a square/pulse wave. Messing with the "steps"...

Have a look at the guitar echo here for ideas http://www.spinsemi.com/forum/viewtopic.php?t=124 , if you set it to maximum feedback it does what you're trying to do.

I think your pot scaling is wrong, the maximum length is 32767 so to get to 8148 you need to deivide by 4 not 2. What's probably happening now is once you get past half way you'e gone outside the buffer.

The way you've done the code for the pot it's just stuck at the end of the program and doesn't do anything. What the code does is read the value from the pot and writing it to the delay memory address pointer. In order to make it do anything you then need to read from the address pointer instead of ...

I don't know if this is the answer to your problem but on the pitch echo program the pitch shift is on one channel and the echo is on the other, so if you only use one output you may only get pitch shifting. Presumably the same thing would happen if you only use one of the inputs. Any problems with ...
